Appliooflonloetober a shim is Chins. (a. see-u) This type of dispenser is operated by rotating an mend head or knob, and is generally known as a swivel-type lipstick container.

One of the objectionable featuresof the above type of lipstick container is that frequently when packed for shipment, or carried around in a hand has, or idly manipulated the members composing the container are liable to be accidentally rotated in relation to eachother with theresult that the cosmetic is forced into contact with the inside of. the cap disfiguring and soiling the work- 2 mg parts and deforming the shaped end of the cosmeticto the annoyance of the user and to the prejudice of the market.

It is,therefore, the main object of this inven tion to provide a cheap and simple means by.

which the unintentional movement of the'cos- 1 metic stick in its casingis eflectually prevented.

' .To this end a cosmetic container of the above nature, which may be a stock article, is formed lwith a locking element whichis actuated by the cover. when in an assembled position to prevent theelevation of the cosmetic container regardless of any rough usage to which the closedarticle is subjected.

The invention includes a tongue or lug mem- I ber formed out of the body casing adjacent its 7 lower endand adapted to be sprung inwardly into thepathway of one of the rotating members within the container, and with reference par: "ticularly to the preferred form; in the pathway of the helical groove through which the elevating pin rises upon therotation of theoperating head.

o Thelug is forced inwardlyupon the assembly of 1 the container cover and by its respective interlocking action prevents such relative turning of any of the parts of thecontainer as would cause the cosmetic stick to elevate and jam into the cover.

with these and other objects in view the in- I vention presents a very'simple structural form as will be more fully disclosed in connection with the accompanying drawing and set forth in the annexed claims. I I

Referring now to the'drawing in which like numerals refer to corresponding parts throughout the several views:

The numeral ll refers generally to a dispensing container comprising anoutside tubular casing and an inside shell I! rotatabiy mounted therewitbin. Disposed between the casing i I and the shell l2 and adapted to be retained and carrled by the-outside casing Ii is a sleeve member ll having a helical groove or slot ll extending from end to end thereof.

The base or lower end of the inside shell I! is provided with an integral head I! of a diameter slightly larger than the outside diameter of the casing Ii. The head I! is preferably provided with a knurled surface as shown in Figs. 1 and 2 to assist in manipulating the same; but it is to be understood that the head it might be made as well of polygonal or any other shape for this purpose within the scope of the invention. The

upper end of the inside shell I2 is formed with an outwardly projecting annular rib It which is adapted to overlie the upper adjacent edge of sleeve member It to retain the same therewithin against axial movement.

Mounted to slide within the inside shell I: is a cosmetic stick carrier in the form of a cup [1 in whichis held a cosmetic stick indicated by the numeral II. The inside shell 12 is formed with a flongi-tudinal slot ll extending substantially the entire length of the shell and within which is adapted to slidably engage the head 2| of a pin ll secured to thecup 'il as best shown in Figs. 3 and 4. The pin 2| customarily projects a substantial distance within the cup to be embedded within the material of the cosmetic stick as a better means for holding the stick ll within 'thecup ll. Thehead 2| oi'thepinil lsadapted to project beyond the slot II a distance sumcient to engage within the helical slot of the sleeve I I previously mentioned. From this construction it will be evident thatthe mere rotation of the inside shell I! relative to'the outside casing ll through the manual operation of the head II will positively project andretract the cosmetic stick ll carried by the cup H.

The forward end of the outside casing ii is rounded'inwa'rdly as at 22 to provide for a smooth suriacesurroundingtheopeningintheendof the container through which the stick I! must protrude in use. The container-l0, when the cosmetic is withdrawn and not in use, is adapted to be closed by a telescoping closure cap 23 designed to slip over substantially the entire length of,

Now, in accordance with thisinvention there is provided a very practical and novelmeans whereby the inside shell I2 and complementary operating head i5 are interlocked against rotation within the outside casing ll upon the mere assembling of the cap 23 upon the container l0, thus preventing accidental longitudinal movement of the stick carrying cup H. To this end there is provided in the outside casing ll, adjacent its lower end, a cutout longitudinal slot 24 angularly positioned so as to permit said slot to be disposed in substantial coincidence with the angular inclination of the helical groove l4 ofthe sleeve member l3 there underneath. A

tongue or lug member generally indicated by the numeral 25 is provided being preferably formed out of a part of the metal stock that'was pierced out to create the slot 24 and being integrally connected to the shell II at the upper short edge of said slot. 24. The tongue is proportioned to extend substantially the entire length 'of the slot 24 and in spaced relation to the longitudinal adjacent edges thereof.

When the parts are assembled in proper relationship the slot 25 as mentioned above must be positioned to coincide with the helical groove ll of the sleeve member l3 so as to bring the axis of the tongue 25 into substantially parallel alinement with the axis of said helical groove ll.

In order to give the tongue 25 a resilient cast the longer proximal end 26 of said tongue 25 is biased outwardly from the normal cylindrical surface of the shell II and the shorter distal end 21 thereof is given a reverse or inward bend thus producing an intermediate humped portion 28 that will serve in the manner of a cam as will be later described. The humped portion 28 is capacitated to spring and project outwardly beyond the circumferential plane of the outside casing II when the cap is removed from the container. When in this position the distal inturned locking end 21 of the tongue is removed from the path of the helical groove l4 permitting the head. 20 of the pin 2| to pass unobstructed upwardly therethrough coincident with the manipulation of the operating head l5.

When the cap 23 is being assembled into-position the tongue 26 with its humped portion 28 will be forced inwardly by reason of the fact that the advancing edge of the cap easilyv cams over the upper inclined edge of the proximal end of the tongue 26 and disposes the locking end 21 fully within the helical groove M. It should. be here understood that before the cap 23 is assembled in place the carrier cup should be retracted to its innermost position with the head 20 of the pin 2| located at the lowermost end of the vertical slot i9. g

Thus, it will be apparent that any attempt either accidentally or willfully to manipulate the head l5 when the cap 23 is in assembled position will cause the head 20 of the pin 2| to abut against the locking end 21 of the tongue 26 and cause the entire container unit I0 to rotate within the cap member 23, and in no way disturb the retracted position of the carrier cup IT.

The modified form shown in Fig. 5 is quite similar to the preferred form except that the vertical projections or ribs 30, the upper end of which may serve as a rest or support for the sleeve member l3. Adjacent the lower end of the tubular casing II is a locking tongue member 3| sprung out and constructed generally in like manner to the tongue 25 of the first form except for the fact that it is disposed in a vertical position. One advantageous feature of this modified construction is that it is not necessary to aline and centralize the tongue with the helical l0 groove II in the assembly operation.

When the cap 23 is assembled into place the tongue 3| will be sprunginwardly carrying the lower end thereof into the lateral rotating path of the ribs 30 so that the whole unit will be car- I ried about within the cover 23 with no danger of elevating the carrier cup even if the head end l5 should he accidentally twisted. It is also within the purview of this invention to provide slots or piercings in the inside shell I! in place of the ribs-in which the tongue 3| can-equally well cooperate to accomplish the same locking function.

Before concluding this specification it is here pointed out that in constructing the preferred form of this locking feature noauxiliary-parts have to be added to the device to effect the desired results but a. stock lipstick is taken and by merely forming a, tongue member out of one of the component shells of the container a very cheap and satisfactory locking device is produced. While only two forms of this invention have been shown and described, it will be understood that other changes and variations might be made in the specific constructions shown and described without departing from the scope of the invention as defined in the appended claims.
